The primary object of the invention is the pro- Similar reference characters indicate corre- 5 vision of a control or switch of this character, sponding parts throughout the several views in wherein the user or operator of an automobile the drawings. can conveniently and with dispatch cut out the Referring to the drawings in detail, A desigelectric system from operation as may be installed nates generally a portion of the body of a motor 10 in the automobile, to avoid current leakage and vehicle or automobile, B the starter and C the 10 consequently drain upon the battery, especially electric storage battery, respectively, these being when the vehicle is left standing and also to of conventional type and constituting no part of eliminate the possible theft of such vehicle, the the present invention except for an illustration control or switch being of novel construction. of the use of the control or switch hereinafter Another object of the invention is the provifully described. 15 sion of a control or switch of this character, The control or switch constituting the present wherein the same can be mounted local to or invention comprises a circular shell or body 10 upon an electric battery as arranged within a in which is arranged a resilient bowed switch motor vehicle, so that the circuit including said blade 11, one end being fixed by a binding post 12 battery can be opened or closed and the same with which is engaged a terminal clamp 13 of the 20 conveniently managed by the operator or driver lead 14 connected with the starter B. The switch of the vehicle, the control or switch being conblade 11 is engageable with a contact 15 on a structed for manual operation and simple in its binding post 16, the same having fitted thereto construction, thoroughly reliable and efficient in the clamp 17 which is engaged with the positive its purpose, readily and easily installed, and inpole of the battery C. 25 expensive to manufacture. Fitted with the shell or body 10 is a bracket 18 With these and other objects in view, the inconstituting a pivot bearing for a swinging lever vention consists in the features of construction, 19, the same being connected with the bracket combination and arrangement of parts as will be or bearing by the pivot 20 for arcuate swinging 80 hereinafter more fully described in detail, illusmovement. The lever 19 is formed with an angutrated in the accompanying drawings, which dislar offset 21 to which is pivoted a spreading arm close the preferred embodiment of the invention, 22 having fast thereto an insulating piece 23 and pointed out in the claim hereinto appended. provided with a nib 24, the latter engageable in a In the accompanying drawings: suitable hole 25 in the blade 11, so that on the Figure 1 is a fragmentary ertical longitudinal swinging of the lever 19 in one direction the said 35 sectional view through a motor vehicle showin blade 11 will be distorted for disengagement with the control or switch constructed in accordance the contact 15, thereby breaking the circuit of with the invention arranged with r lati n o h the electric system for the automobile from the S a e y, With the Operating medium P battery C, the circuit being closed when the blade 0 tloned conve ient y o use 0 h p a 11 engages the contact 15, as should be obvious. driver of the vehicle. Connected with the shell or body 10 at the Figure 2 is an a d horizontal Sectional proper locality by a coupling 26 is a conduit 27 view through the control or swit h showing i housing a pull and push rod or wire 28, the condetall th make-up of the some and th a n duit being suitably trained to the dash 29 of the of assembly with respe to the battery and the body A of the motor vehicle and made fast to said 45 electric Sy an automobiledash in any suitable manner, while the rod or Figure 3 is a Sectional View On the line of wire 28, which is of the flexible kind, as carried Figure 2 loo ng i direction 0f the within the conduit has at its free end a hand knob Figure 4 is a vertical transverse sectional view 30 so that thi wir or d a b manually tak sub y all an angle to the Section in manipulated for a pull and push action and under Figure 3. v such action the control or switch can be operated Figure 5 is another vertical transverse sectional by separating the blade 11 from the contact 15 view through the control or switch. or the engagement of this blade with said contact Figure 6 is a perspective view of the throw for the opening and closing of the electric cirlever of the switch or control. cuit for the motor vehicle. 55

Located within at shell or body 10, next to the switch blade 11, is a ground spring 31 with which is connected the ground wire 32 related with the frame of the motor vehicle, so that the back flow of current caused by a generator (not shown) in the electric system or the motor vehicle will be grounded through the ground wire 32 as the back flow will be eflected by the contact of the blade 11 with the ground spring 31.

When it is desired to disconnect all the battery current from the motor vehicle it is only necessary to manually pull upon the knob .30 and through the instrumentality of the pull and push rod or wire 28 the blade 11 will be caused to break from the contact 15 and engage with the ground spring 31, thus grounding the back flow of current caused by the generator. The shifting lever 19 throws the arm 22 past center, thus locking the said lever 19 in a position by the spring resistance of the blade 11 and in this manner holding the said blade 11 engaged with the ground spring 31 so that the battery current will be shut oil from the electric system for the motor vehicle.

mechanics when making repairs to the electric system, the generator and starter. when the motor vehicle equipped with the control or switch is parked and the battery cut out thereby it is impossible for a malicious person to waste current by the blowing of the horn or injury resultant from actuating the starter or the theft of the vehicle, the control or switch being beneficial for disconnecting current from the battery instantly when the vehicle gets out of control while driving.

What is claimed is:

A device of the kind described comprising a shell, couplings arranged opposite each other on said shell and one being adapted for engagement with a positive pole of a storage battery on the detachment of a lead to a starter therefrom, the other coupling being engageable with the said lead on said starter, a yieldable switch blade for normally bridging the space between said couplings and forming a connection therebetween, a swinging lever within the shell, a spread arm pivotally carried by and insulated from the lever to move the switch blade for disconnection between the couplings, the blade being formed with an aperture, a nib on the spread arm and fitting in the aperture and a remotely operated means controlling the said lever.
